Jaylen Brown finished with 13 points, five rebounds, and four turnovers as the Philadelphia 76ers lost to the Boston Celtics 123-101 in the first matchup between Brown and Jayson Tatum of the season.

Brown struggled throughout the game, with coach Nick Nurse admitting that he "had a rough night."

"I was looking forward to this. I was looking forward to playing well, but s--- happens," Brown said. "Get ready for the next one, I guess."

Brown, who also finished with a game-worst minus-27, ignored Tatum before tip-off.

"I'm just focused on doing what's best for my team," Brown said when asked about the moment. "Everything else was just, to be honest, I wasn't paying attention, but credit to Jayson; he played well tonight."

Tatum finished with 21 points and six rebounds while also downplaying the significance of the matchup.

"No headlines about anything like that," Tatum said. "I was just getting ready for the game, ready for jump ball, go out there, compete, have some fun, and try to get a win."

Brown came into the game averaging 21.5 points and 6.5 rebounds on the year. 

Brown denied that his emotions got in the way of his performance.

"I didn't have any emotion. I was locked in. I was focused, I was ready to go," Brown said. "Foul trouble kinda of took me out of my rhythm a little bit. I had to sit for a while, and we didn't execute as well as they did."
